Question

The wave mechanical model of an atom is based upon

• A. de-Broglie concept of dual character of matter
• B. Heisenberg’s uncertainty principle
• C. Schrodinger’s wave equation
• D. All the three above

Answer 1

The correct option is D

All the three above

Explanation for correct option:

(D) All of the above:

• de Broglie equation is used to solve the wavelength of the moving electrons. As per the de Broglie concept, the wave-like behavior of the particles with certain finite wavelengths consolidates the wave-particle dual nature of such particles.
• Heisenberg's Uncertainty Principle suggested that the position and momentum of a particle cannot be measured with precision simultaneously, thereby supporting the wave-particle dual nature of such particles.
• The wave mechanical model developed by Schrodinger is based on the particle and wave nature of electrons. Thus, Schrodinger's equation defines the wave/state function of the quantum mechanical system.
• Hence, the circular motion of the electrons around the nucleus can be considered as generating standing waves whose amplitude is independent of time and function of distance from a fixed point.

Explanation for incorrect options:

Since, the correct answer is all of the above. Therefore, solo options (a), (b) and (c) stand incorrect.

Hence, option (D) is the correct option.
